[Bioc-devel] excessive downloading of packages?

Perhaps this a user-settable thing I'm missing, but now it seems that  
every time I call getBioC I download all of the packages. I'm using  
getBioC v0.1 from the getBioC-1.6.R URL. Isn't there some sort of  
package cache that can be used for this?

(Also, the fact that the build script is v0.1 and we're using  
getBioC-1.6 might confuse users a bit)

Thanks,

Cyrus
